Each team will be assigned 5 secret target words. The round will contain a combination of Text Prompt Challenges and Image Challenges. The Judge will specify which target words are to be handled through each format. 1. Text Prompt Challenge For the words assigned to the text-prompt challenge, teams must craft prompts that subtly lead an LLM to talk around the target word without directly revealing it. No root word, variation, or derivative of the target term may be used in the prompt. The prompt should be interpretable by the LLM and produce a relevant response. However, it should be indirect and misleading enough that the opposing team cannot easily identify the target word. Power Prompts may be provided during the round and must be used according to the twist assigned by the Judge. The opposing team will then attempt to identify the target word from LLM's response. 2. Image Challenge The remaining target words in the round will be handled through an image-generation challenge. For each assigned word, the team will receive a twist that determines how the image must be created. The team must use the twist to generate an image that represents or hints at the target word without making it immediately obvious. The generated image will then be shown to the opposing team, who must attempt to identify the target word from the image. The challenge is to create an image that gives enough visual clues to be solvable while remaining sufficiently indirect to make the opponent think. 3. Guessing Phase The opposing team will be given a word bank containing 100 possible words. They must use this word bank to identify the target words represented by the LLM text responses and generated images. The word bank will contain the target words belonging to both teams, along with other possible words.
